T at whom it may concern.

Be it known that I, LONGLEY Lnwrs SAGEN- DORPH, a resident of Cincinnati, Hamilton county, Ohio, have invented certain new and useful Improvements in Metallic Roofing, of which the following is a specification.

The object of my invention is to produce a cheap and simple means for uniting sections of metallic roofing.

In the accompanying drawings, forming part of this specification, Figure 1 is a top view of a blank of sheet metal, showing the cuts employed in making my sections. Fig. 2 is a top view of part of a section, showing the lips folded back on the sheet. Fig. 3 is a perspective view of part of a complete section. Fig. 4 is a perspective view illustrating the method of uniting two sections. Fig. 5 is a cross-section through one of the joints holding two sections together. Fig. 6 isa perspective view of a modified form of section embodying myinvention. Fig. 7 is atop view of the shingle shown in Fig. 6. Fig. 8 is a perspective view of part of a roof partly covered with my improved roofing. Fig. 9 is a perspective view of a section made in the preferred form-viz., with a teat-crown, hereinafter fully set forth. Fig. 10 is a perspective view showing two sections-such as are shown in Fig. 9 united, one of the sections being partly cut away. Fig. 11 is an enlarged crosssection through a joint uniting the sections shown in Fig. 10. Fig. 12 is a view in elevation of a tool for eountersinking the cleat formed from the end of the sheet and extending over the raised standing seam or teat-crown of the adjacent following sheet.

The sections of this roofing are similar to each other. The blank A, of sheet metal,fro1n which a section is formed, is shown in Fig. 1. Slits are cut into one edge of the sheet, forming thelips or cleats B, and between them the leaves O. The leaves are now bent back onto the sheet, as shown in Fig. 2, thus forming cleats, and the two ridges D and E are bent into the sheet. Preferably the top of each of these ridges terminates in a secondary ridge, forming a teat-crown, as shown in Figs. 9, l0, and 11. The ridge D has its outer lip, (Z, preferably a little shorter than the inner side of (No model.)

the ridge. The ridgeEis preferably so placed that its summit coincides with the line at which the leaves 0 are folded back.

In uniting two sections, the ridge D of one is placed over the ridge E of the other, and is there secured by bending the cleats B up over it, as shown in Fig. 4.. The ridges are now compressed with squeezing-tongs, forminga very strong and tight scam.

I I sometimes provide each section with a central ridge, F, lying midwaybetween the ridges D and E, and with the short ribs G, (shown in Fig. 6,) and which, like the ridges, are hollow. Vhen the sections are provided with thethree ridges and the ribs, I usually make them much smaller than when the two ridges alone are employed. These smallsectionsltcrm shingles.

In joining adjacent courses of sections provided with the three ridges and the ribs, the sections of the upper course overlap those of the lower in such way that the ridges F of the upper course of sections overlap the joint formed by the ridges D and E of the lower course of sections, and the joints formed by the ridges D and E of the upper course of sections overlap the ridges F of the lower course of sections. This arrangement is well shown in Fig. 8.

The tool for shaping the cleats over the joined ridges consists of the shank t, at one end of which is the head t and at the other end the head if. A groove, 1, conforming to the shape of the ridges of the roofing, is cut across the head The other head, Z", is fiattened to receive blows from a hammer.

It may be remarked, in this connection, that the advantages of the teat-crown arrangement shown in Figs. 9, 10, and 11 is that it prevents lateral displacement of the sections and cleats, and when countersunk the cleat forms a perfectly weather-proof joint for the seams of each of the joined sections.

While the various features of my invention are preferably employed together, one or more of them may be used separately, and in so far as applicable one or more of said features may be used in connection with roofing material other than of the description herein specifically set forth.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1. Asheet'or section of metallic roofing provided with a corrugation or ridge, E, and having a cleat, B, formed by cuts made into the sheet transversely to the direction of said ridge, in combination with a section of roofing having the corrugation or ridge D overlapping the ridge E, the two sections or sheets being held together by the said cleat bent in the line of the cuts, and extending over the ridge E and beneath ridge D, and thence back over the ridge D, substantially as set forth.

2. The sheet or section of metallic roofing having ridge E, provided with secondary'ridge or crown, and the cleat B, formed by cuts made in the sheet transversely to the direction of said ridge, and the sheet or section having ridge D, provided with secondary ridge or crown, the cleat B bent back over the ridge E under ridge D, and then back over the latter, as set forth. 7

3. The sheet or section of metallic roofing having ridge E, provided with secondary ridge or crown, and the cleat B, formed by cuts made in the sheet transversely to the direction of said ridge, and the sheet or section having ridge D, provided with secondary ridge or crown, the cleat B bent back over the ridge E under ridge D, and then back over the latter,and conforming to the shape of said ridge D and its secondary ridge or crown, substantially as and for the purposes set forth.
